Fluid catalytic cracking - Wikipedia
Fluid catalytic cracking (FCC) is the conversion process used in petroleum refineries to convert the high-boiling point, high-molecular weight hydrocarbon fractions of petroleum (crude oils) into gasoline, alkene gases, and other petroleum products.
Catalytic Cracking of Crude Oil: Mini Review of Catalyst …
2022年5月4日 · Developing active and selective catalysts for crude oil cracking that fit into the current refinery system will go a long way in saving cost and time. In this review, catalyst formulations for the conversion of crude oil to light olefins have been discussed under the classifications: zeolite components, tuning of zeolite porosity, and matrix ...

2020年9月25日 · Hydrocracking is a process by which heavy petroleum products are converted into lighter chemicals with lower boiling points in the presence of hydrogen and a suitable catalyst.
Fluid Catalytic Cracking (FCC) in Petroleum Refining
2015年1月1日 · Thermal and catalytic cracking processes in petroleum refining reduce the molecular weight of these heavier constituents and produce more valuable lighter products such as LPG, gasoline, and diesel fuels. Catalytic cracking was …
Catalytic Cracking - an overview | ScienceDirect Topics
Catalytic cracking is an ionic process involving carbonium ions (hydrocarbon ions having a positive charge on a carbon atom) and are produced by: (1) addition of a proton from an acid catalyst to an olefin, (2) abstraction of a hydride ion (H−) from a hydrocarbon by the acid catalyst or by another carbonium ion. From: Fouling in Refineries, 2015.
Recent Developments in FCC Process and Catalysts
2021年4月2日 · The fluid catalytic cracker (FCC) is one of the most integral conversion processes in a modern petroleum refinery. Colloquially known as the workhorse of the refinery, it converts low-value vacuum distillates into high octane gasoline and LPG by cracking heavier hydrocarbon molecules in the presence of a fluidized bed of particulate catalyst.
catalytic cracking processes in petroleum refining reduce the molecular weight of these heavier constituents and produce more valuable lighter products such as LPG, gasoline, and diesel fuels. Catalytic cracking was first commercialized in 1936 by Eugene Houdry.
Role of Catalyst in Optimizing Fluid Catalytic Cracking …
The cracking experiments were performed in an advanced cracking evaluation fluid catalytic cracking (FCC) laboratory unit at 527 °C, 30 s catalyst time on stream, and catalyst-to-oil (CTO) variation between 3.5 and 7.5 wt/wt The two high UCS lower porosity catalysts were more active and more coke selective.
Fluid Catalytic Cracking (FCC): Catalysts and Additives
2015年6月15日 · The fluid catalytic cracking (FCC) unit is the primary hydrocarbon conversion unit in the modern petroleum refinery. It uses heat and catalyst to convert a variety of high molecular weight feed types (eg, gas oils, cracked gas oils, deasphalted gas oils, and atmospheric/vacuum resids) into lighter, more valuable products such as gasoline, light ...
